[linux mint]Win7 + Linux mint安装（含eclipseericandroid studiopycharm等安装）

eric

这回安装eric，前面觉得linux mint界面，额……没有那么喜欢吧，想试下其他发行版，结果发现还是linux mint对我的老本lenovo v360支持的好。又折腾回来，结果在安装Eric的时候，各种出错，明明更新了pip，包也提前下载好了，结果在安装的时候依然提示包不存在，无法安装。这个我放在最后说，先来正确的步骤。

1、下载eric

官方地址：http://eric-ide.python-projects.org/

下载地址：http://eric-ide.python-projects.org/eric-download.html

下载地址页面有一个大大的Download，应该都能找到。

下载有些慢，可以考虑使用aria2下载，会快一些

2.安装qt组件

sudo apt install qt5-default qttools5-dev-tools

3.安装eric依赖

python3 -m pip install <包名>

建议用以上命令先将eric相关依赖安装

4.解压eric

放在一个目录，建议/opt

sudo mv <eric目录> /opt

5.进入eric目录，并安装

sudo python3 install.py

 下面说说pip 的事儿，前面安装的时候是这个样子的：

python3 ./install.py

就是明明已经用pip安装，但在安装eric的时候，就是提示不对，没有依据，但估计是linux自带多个版本python，在安装pip时多个版本之间的问题。

解决问题的方法就是使用pip的时候，通过python -m调用，使用python的版本选择pip的版本

python -m pip install      #对应python2.X的pip
python3 -m pip install     #对应python3.X的pip

建议先使用pip安装完相关依赖安装，再安装eric。

在安装过程中，会提示下面的内容。

 WARNING: The scripts pylupdate5, pyrcc5 and pyuic5 are installed in \'/home/lee/.local/bin\' which is not on PATH.
 Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

 需要修改/etc/profile，将相关路径加入path

方法参见链接，这个是修改JAVA_HOME的PATH     https://www.cnblogs.com/jpfss/p/7895944.html

把要加入path的路径起个名字就行了。
